unit vector lies in the xy plane, at an angle of 145 degrees from the +x axis, with a positive y component. What is the unit vec

Fittoniya [83]

Answer:

$-0.82i+0.57j$

Step-by-step explanation:

We are given that a unit vector A which lies in the xy-plane.

Unit vector:It is that vector whose magnitude is equal to 1.

$\mid A\mid=1$

$\theta=145^{\circ}$

We have to find the unit vector.

x-component of unit vector= $A_x=\mid A\mid cos\theta$

x-component of unit vector= $A_x=1cos145^{\circ}=-0.82$

y-component of unit vector= $A_y=\mid A\mid sin\theta=1\times sin145=0.57$

Unit vector ,A= $A_xi+A_yj=-0.82i+0.57j$

Hence, the unit vector = $A=-0.82i+0.57j$

Volume of the cone:

V1=(πr²h)/3
V1=(π)(20)²(25)/3
V1=10,471.97

Volume of the larger cylinder:

V2=πr²h
V2=π(20)²(150)
V2=188,495.55

Volume of the smaller rectangular prism:

V3=lwh
V3=(65)(45)(120)
V3=351,000

Volume of the larger rectangular prism:

V4=lwh
V4=(55)(45)(150)
 V4=371,250

Volume of the rectangular pyramid:

V5=(lwh)/3
V5=(55)(45)(35)/3
V5=28,875

Volume of the smaller cylinder:

V6=πr²h
V6=π(20)²(95)
 V6=119,380.52

Volume of the hemisphere:

V7=2πr³/3
V7=2π(20)³/3
V7=16,755.16

Total volume of the castle:

Vt=V1+V2+V3+V4+V5+V6+V7
Vt=1,086,228.2
